EYEGLASSES ANB MNTING.

Eyeglasses and Mountings, and do herebyy declare that the following is a full, clear,

- and exact description thereof.

uThe object 'of my invention has been to provide an eye-glass and mounting which shall have, among others, any or all of the following advantages: that it shall permit the'use of relatively large lensesgthat it shall reduce the-pupilary distance of the lenses without in any manner interfering with, or rendering less elective, the bridge and parts which engage the nose; that it, shall hold the glasses securely and preventl any movement in a vertical plane, relative 4to the bridge, even though there should be a slight looseness of the screws o-r corresponding fastening parts; that it shall be so constructed that the pivots of the piv o ted nose-engaging parts cannot escape from position so long as the lenses are secured in position; that it shall permit change in the vertical pupilary position' relative to the bridge byl a mere rearrangement of the same parts and witho-ut requiring eXtra parts; that it shall enable the springs of spring-pressed nose-engaging parts to bemore readily assembled than heretofore; and to such ends my invention consists in the eye-glasses and mounting hereinafter specified.

In the accompanying drawings Figure 1 is a front elevation of an eye-glass mountingv and lenses' embodying my invention;Y

Fig. 2 is a plan view of Fig. l; Fig. 3 is a rear elevation of Fig.` l; Fig. 4 is an enlarged end elevation of the mounting itself; Fig.l 5 is an enlarged fro-nt elevation of the mounting itself; Fig. 6 is a view showing 'i the parts of the mounting separated; and 45 Fig. 7 is a view. of a lens alone.

' It is desirable that large lenses be used in eye-glasses in'v order that the lensshall 1 tercept the line of vision, even though the eyes the turned sidewise or up and down, and Without turning the head, but the ordinary eye-glass mountin'gseriously limits the size ofthe lens which may be used because its parts necessarily holdl the. glasses widely apart. It is also desirable that the pupilary distance of the lenses shall be the same as that of the eyes, regardless of the size of the Specification of Letters Patent.

l. have produced :my invention.4

The embodiment of my invention illustrated in the accompanying drawings, is the best embodiment thereof known to me, but it is to be regarded as typical only of many possible embodiments, and my invention is not to be limited to the form shown.z l am'alsoa'ware thatthe various features of my invention may loe used separately,

and with other forms of mounting than that' shown, and my invention is not to be limited to a mounting in which all of the features are present.

ln the illustrated embodiment, the bridge l carries at each end upper and lower pairs of'ears 2 and 3, respectively, which ears are preferably formed from` a sheet of metal with av plate 4t that is secured to the end of the bridge. The eye-glass is secured between the said pairsy of ears, as byscrews 5 and (i, respectively, the glass for that purpose being provided with two holes 7 and S, respectively. In order that the glass may apesl preach the nose as closely as possible, and

' thus brings its pupilary center inward, it Iis provided with a' notch' 8, which receives within it the plate 4. `Fach plate d is prof vided with upper and lower horizontal ears w 9 and 10 which project in the plane of the p lens, .away from the bridge, and such ears carry a vertical pivot-pin 11 whichis seated in holes in the ears and held inplace by the upper and lower walls of thevnotch in the lens, the said notch being made deep enough to receive the said ears. The pivot-pins are for the purpose of pivoting a spring-pressed lever carrying a nose guard. Each lever 12 'carries a sleeve 13, preferably projecting from one side only of the lever, the said sleeve being journaled on the said pivot-pin. The rear end ofthe lever has a nose guard 14 pivoted on it in the usualmanner, and the front end of the lever is formed into a handle l5 adapted to be engaged by: the thumb or linger in applying the glasses to the nose. v

- position is a other end 18 engaging the lever incassa A spring 16 has its coil` mounted upon the said sleeve and has one end l? engaging a stationary` part, such as the lens, and its so that the spring tends to throw the nose guards against the nose.

My eye-glass and mounting have, others, the following advantages: As the lenses approach closely to the nose, not being held away by, the bridge construction, lenses of large diameter can be used.' For the same reason the pupilary distances of the lenses can be made the same as those of the eyes, within much wider limits than with the ordinary eye-glass mounting. By simply reversing` the levers so that the sleeves are on the lower sides of the levers, instead of the upper sides, as shown in the drawings, so the vertical pupilary position of the lenses can be varied. If the levers are so reversed the nose guards would usually be bent anew toA t the nose, or they could be reversed on the levers. The sleeves afford a long firm bearing for the levers, which will not be materially loosened by any ordinary wear. The lenses are secured to the bridge at two sep; arate points (by the two separate screws) so that no ordinary looseness of the parts will permit any vertical movement of the lens relative to the mounting, and a very firm securement is obtained. The pivot-pins of the levers (beingso retained above and below by the walls of the notches in the lenses) can not come loose unless the screws be takenout ot the lenses. As thesprings can be secured upon the levers for the purpose of assembling, merely by placing them upon the sleeves, the placing of the pivots in relatively simple and ,easy oper-- ation. Notwithstanding all of the above ad.- vantages, the extreme width or' my eye-glass mounting is not greater than that of vthe ordinary mounting.

The levers per .se are not claimed in this patent but will be made the subject of a separate patent.

. l claim:

1. Eye-glasses consisting oi' the combina among vtion of lenses, a bridge and nose engaging levers, said lenses. having notches in the edgesl nearest said bridge, and said levers being mounted in said notches.

2. Eye-glasses consisting, of the combination of lenses, a bridge and nose engaging levers, said lenses having notches in the edgesnearest said bridge, and the ulcrums of said levers being mounted in said notches. 3., Eye-glasses consisting .ofthe combina.-

.bridge having means tion or lenses and a bridge, said bridge having upper and lower ears secured to each end thereof, a pin passing through each of said pairs of ears, nose engaging levers mounted upon said pins and between said ears,rand lenses having notches in which said ears are received.. j

a. Eye-glasses consisting of the combination of lenses and a bridge, said bridge having upper and lower pairs of ears secured to each end thereof, pins'passing through each or' said pairs of ears and the corresponding lens, upper and lower horizontal ears secured to each end ot said bridge and projecting into a notch in the edge of the correspending lens, pins mounted in said ears, and nose engaging levers mounted on lsaid pins.

5. Eye-glasses consisting ofv the combination of lenses and a bridge, said bridge having upper and lower pairs of ears secured to each end thereof, pins passing through each otsaid pairs of ears and the corresponding lens and nose-engaging levers mounted between said ears and within the peripheries of said lenses.

6. An eye-glass mounting consisting of a bridge having means for supporting the lenses, and havinga pair of horizontally projecting ears at each end of the bridge, a journal pin mounted in each of said pairs of ears, and a hose-engaging lever journaled on said pin, said pairs of horizontally project- .ing ears being received in a notch in the correspondinglens.'

7 An eye-glass mounting consisting of a for vsupporting the lenses, and having a pair of horizontally projecting ears at each end of the bridge, a journal pin mounted in each of said pairs of ears, 'a nose-engaging lever journaled en saidl pin, and a lens notched to tkover said ears, thereby securing said pin in its ears.

8. Eye-glasses consisting of lenses and a bridge, said bridge vhaving upper and lower pairs of ears at each end and pins passin through said ears and said lenses, said bridge also having horizontally projecting vears carrying .a pivot-pin, said lenses being notched to tit over ysaid lastmentioned ears,

and nose-engaging levers mounted on said v 110 pivot-pins.

in testimony that I claim the foregoing I have hereunto set my hand. A
